Appointments are not usually necessary. It is recommended you bring a completed test requisition form from your healthcare provider and a copy of your medical insurance card in order to expedite your visit. Our Patient Service Centers are busiest in the early morning when patients who are required to fast for testing often choose to arrive. Your wait will usually be shorter after 10AM. You may wish to consider arriving after that time. We are pleased to offer online appointment scheduling for several of our locations. In 2007, we will be rolling out this capability nationwide. You can see which locations offer appointments by accessing our Patient Service Center Locator. If the results display a Make appt link, the location offers online appointment scheduling.
